Crossmember for DSE Sub and Holley specific parts? - Lateral-g Forums

**130fe** · #1 03-15-2021, 08:22 PM

Is anyone running these specific parts in a first gen?

Trying to figure out which Holley Trans crossmember works with these parts-

1. DSE sub, LS3/T56 magnum
2. 60404 mounts
3. Holley headers for DSE sub
4. Holley exhaust for DSE sub and quadralink.

I tried using the Holley crossmember (for the stock subframe) and it doesn’t align and one of the T56 case tabs interferes with it. Holley doesn’t make a crossmember for the LS conversion with a DSE sub....

I have a DSE sub and I’m using the hooker black heart. Lsx427 and t56 magnum.

Will, which crossmember are you using? The Holley 12626 one (their standard first gen LS one)?

Honestly i'd have to go back and look, it was when that cross member first came out and installed probably back in 2016-ish timeframe. I've had it out and back in several times since then with no issues.

I will say i did have to slightly oblong the holes on the mount to fit, but it was less than 1/4". I'll take a look later to see if i can get pics.

And this is with the DSE setback mounts on their frame as well.

Maybe an obvious question/scenario, but have you looked at your mount to see if it has offset mounting? I'm using a mount with two bolts through the crossmember, and cant remember if they're centered or not, but i dont believe they are.

I’m using the same setup but with DSE headers and DSE setback motor mounts and I picked up a Bowler crossmember and it works great. I was in their shop for something else and they happened to have one that the powder coating was chipped on so I picked it up at a discount expecting to have to mod it. At the time they said it was for a BBC with T56 but there was no wrapping or part number on it. Only thing I had to do was oblong the holes and it fits perfectly.
